I could of sworn that on the rooftop all the named attacks embued in CoA such as Tatsumaki and Hiryu Kaen Enma was emphasized. If that not the case then that just feeds into my argument. AdCoA usually is showcased with lightning coming off of a weapon, yet that wasn't the case for Zoro.The only difference between Dead Man's Game and every other attack Zoro executed is that he went Asura to perform it.
Enma was emphasised in Hiryuu Kaen, Tatsumaki, and even for Dead Man's Game.
I don't see how your argument is credible.
